It doesn't take long for the perceptive Bible reader to realize that there is a Kingdom of God and a Kingdom of Heaven, mentioned in the pages of the B'rit Hadashah, the New testament. Some say they are the same. Most agree that the Kingdom of Heaven began at the time of Y'shua, Jesus and continues through the end times and into eternity. This is supported by Matthew 11:12.
However, nestled in the Matthew 25:34, we find this reference to a separate Kingdom beginning immediately after the end times.
“Then the King will say to those on his right, ‘Come, you whom my Father has blessed, take your inheritance, the Kingdom prepared for you from the founding of the world."
We know that the Kingdoms are not straightforward. They are mysterious and contains secrets. Matthew 13:11.
"...it has been given to you to know the mysteries and secrets of the Kingdom of Heaven."
The references to the Kingdom of Heaven are contemporary, not future, and contains warnings concerning the infiltration of Satan and his cohort. While the Kingdom of God can be seen as synonymous with the Kingdom of Heaven, in numerous coinciding verses, we can also see that the Kingdom of God is also in the future, with verses like Mark 14:25.
"Yes! I tell you, I will not drink this ‘fruit of the vine’ again until the day I drink new wine in the Kingdom of God.”
and Luke 13:28-29, which could be seen as pointing back to the Kingdom, mentioned in 25:34.
"You will cry and grind your teeth when you see Avraham, Yitz’chak, Ya‘akov and all the prophets inside the Kingdom of God, but yourselves thrown outside. Moreover, people will come from the east, the west, the north and the south to sit at table in the Kingdom of God."
Could the answer to this question be found in Ephesians 5:5, where it hints at the dual kingdoms of the Messiah and God?
"For of this you can be sure: every sexually immoral, impure or greedy person - that is, every idol-worshipper - has no share in the Kingdom of the Messiah and of God."
Could the Kingdom be representative of the destinies of the Bride of Christ and the Wife of Yahweh?
Or could it simply mean the Kingdom has it's beginning in the Messiah and will be fulfilled, immediately upon the return of the Son of Man?
Only the Spirit of God will lead you into the truth and reveal the mysteries/secrets of the Kingdom(s).
